Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Tepetiltic. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tepetiltic page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The oval-shaped, 5 x 2.5 km Tepetiltic caldera, seen here from the shore of a lake that occupies the older NE side of the caldera, was formed during two eruptive episodes that produced voluminous rhyodacitic airfall tephra and ashflows. Formation of the compound caldera was closely followed by emplacement of two rhyodacitic lava domes on the eastern flank. The low forested hill at the far side of the lake is a lava dome extruded near the intersection of the two calderas. A second dome was emplaced to the left on the floor of the higher SW caldera.

Volcán Tepetiltic is an andesitic and dacitic stratovolcano truncated by an elliptical, 5 x 2.5 km caldera that contains a lake at its NE corner. The compound caldera, seen here from the NE, was formed during major rhyodacitic eruptions that were closely followed by emplacement of lava domes on the eastern flank. A permanent caldera lake (center) occupies the lower NE caldera floor. The small forested lava dome beyond the caldera lake was emplaced near the intersection of the two calderas.

The irregular ridge on the horizon is the SE rim of the compound 5-km-wide Tepetiltic caldera. The NE caldera was offset from the center of the stratovolcano and its rim is lower to the NE (right). The flanks of the andesitic-dacitic stratovolcano are blanketed by deposits of rhyodacitic ash and pumice from the caldera-forming eruptions. Cinder cones on the NW and SE flanks of the volcano erupted alkalic lava flows.

The flat-topped rhyolitic Los Ocotes lava dome (center) was erupted on the southern flank of Tepetiltic volcano about 100,000 years ago and is the youngest product of that complex. Extrusion of the dome blocked drainages to form Laguna San Pedro, out of view to the left. The rim of Tepetiltic caldera forms the right horizon. Los Ocotes is seen here from the SE along Highway 15 where it crosses the blocky andesitic El Ceboruco lava flow in the foreground, which traveled 8 km from Ceboruco volcano.
